Consider wiggle formula $w(t, x)=f(\mathrm{bx}+\mathrm{ct})$ for a transverse wave, where $b$ and $c$ are constants and $f()$ is some arbitrary function. Is this a traveling wave model? If so, in what direction does it travel?
A) In the $+x$ direction.
B) In the $-x$ direction.
C) The wave does not move.
D) In the $y$ or $z$ direction because the wave is transverse.

The wave travels in the $-x$ direction because the argument of the function $f(\mathrm{bx}+\mathrm{ct})$ increases with time $t$ for a fixed position $x$, indicating that the wave peaks move in the negative $x$ direction as time progresses.

Consider Wiggle Formula w(t,x)=f(bx+ct)w(t, x)=f(\mathrm{bx}+\mathrm{ct})w(t,x)=f(bx+ct) For a Transverse Wave, Where bbb And ccc
